Thanks for the tip. I really did the job on mine. First I left it in the car under the hot sun I had a box on top of it to keep it flat, but under the floor map there were some bumps. So I tried to iron the warps out (used foil in between). No luck.
I'll try your idea. I've got nothing to loose now.

My cutting mat was warped by an iron.. yes, i used it to iron .. a brief mistake.. the mat warped.
d.rickman put her own warped Cutting mat outside in the HOT sun for several hours, let it cool completely for several more hours and ... It worked ! Flattened out !
Great hint ! Waiting for one of those last 90 degree days that sneaks up on us this late.
Thanks for the tip !
